Abstract

Official abstract text for this publication.

Provided is an all-solid-state battery with high charge-discharge efficiency. Disclosed is an all-solid-state battery, wherein the all-solid-state battery comprises a cathode comprising a cathode layer, an anode comprising an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer; wherein the anode layer contains at least one selected from the group consisting of a lithium metal and a lithium alloy; and wherein a protective layer comprising a composite metal oxide represented by Li—M—O (where M is at least one metal element selected from the group consisting of Mg, Au, Al and Sn) is disposed between the anode layer and the solid electrolyte layer.

First claim

Opening claim text (preview).

The invention claimed is: 1. An all-solid-state battery, wherein the all-solid-state battery comprises a cathode comprising a cathode layer, an anode comprising an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer; wherein the anode layer contains at least one selected from the group consisting of a lithium metal and a lithium alloy; wherein a protective layer comprising a composite metal oxide represented by Li—M—O, where M is at least one metal element selected from the group consisting of Mg, Au, Al and Sn, is disposed between the anode layer and the solid electrolyte layer; and wherein the protective layer does not contain a polymer. 2. The all-solid-state battery according to claim 1 , wherein a thickness of the protective layer is from 30 nm to 300 nm. 3. The all-solid-state battery according to claim 1 , wherein the M is at least one metal element selected from the group consisting of Mg, Au, and Sn.
